First of all thank you for everybody who replied to the first one. I didnt hop back on, was taking things into consideration. After looking into it I am planning on buying a remanned rear end. I have an 04 f150 with the 5.4. 8.8 with 3.55. I planned on sticking with the 3.55 but was going to go with the limited slip, price difference isnt enough to worry about. I also thought about upgrading to the 9.75. What exactly does this swap entail on the 2004? I have the xlt. From older years it seems like it is just cutting down the drive shaft which might be worth it for the additional strength. Just wanted to know what I was getting myself into here. Thanks guys.
